Description and Introduction

Low-Cost Voltage-Mode PWM Step-Down Controllers The MAX1967EUB+ is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 23V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX® (3mm x 5mm)  

### **Descriptions:**  
The MAX1967EUB+ is a synchronous step-down DC-DC converter designed for high-efficiency power conversion in applications requiring a compact footprint. It integrates high-side and low-side MOSFETs to minimize external component count and improve efficiency. The device operates at a fixed switching frequency of 500kHz, allowing for small external components while maintaining stable performance.  

### **Features:**  
- **Integrated Power MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **High Efficiency:** Up to 95% efficiency for extended battery life.  
- **Low Dropout Operation:** Maintains regulation even when input voltage approaches output voltage.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Small Footprint:** 10-pin µMAX package for space-constrained applications.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Low-Cost Voltage-Mode PWM Step-Down Controllers

Alternative Part Number

  • TPS62130RGTR --: Step-down DC-DC converter in a small package with comparable input voltage range and current capability, widely available and pin-compatible in function.
  • LTC3406ES5#TRPBF --: High-efficiency synchronous buck converter with similar switching frequency and output current, suitable drop-in functional replacement.
  • AP3211KTR-G1 --: Low-cost 1.5A step-down converter with comparable voltage ratings and small footprint, good alternative when cost is a priority.
